What do I need for ATI crossfire?

  1. I'm planning to get a second POWERCOLOR AX3650 512MD2, but I think I lost the bridge from the first one I had. To make matters more confusing, I don't think the bridge even came with the first one, because I checked the contents of it online and it didn't say it came with a crossfire bridge. Also, I heard that for crossfire to work, it just has to be the same GPU, so is it possible for me to cross that card with a POWERCOLOR AX3650 1GBD2 ?

    The two seem the same in every way except for a memory difference.

    There are two ways to link the cards for Crossfire I think; most new cards include the internal bridge. There is another type of bridge that has two DVI adapters to plug into each card which goes outside the case as opposed to linking the tabs inside. You could probably get both types off eBay or something if you don't get one with the second card.

    Those two cards use the same exact GPU so they should work together. I'm not sure which one you should put as Master but I don't think the difference in memory would prevent them from working. I'm 90% sure that they would work in Crossfire, they use the same driver too.

    You can get internal bridges here, but that seems a little pricey imo.

    Okay, reexamining my card, I didn't find any crossfire bridge connectors whatsoever, so it may connect through DVI cords, although is it possible that they don't have to connect at all?

    Now that I have two cards, same memory modules, I don't see the crossfireX tab. Heard it may have something to do with catalyst 8.11
